x402
Unit Converter API is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).
Converts values between units across length, mass, volume, speed, area, data size, time, energy, pressure, and temperature categories, returning the converted value, category, and conversion factor.

How this service works
Unit conversion: length, mass, volume, speed, area, data size, time, energy, pressure and temperature; e.g. '10 km to miles', '72 F to C', '500 MB to GiB', '3 cups to ml'. Returns the value, the category and the factor. $0.01 per conversion.
Output
Returns the numerically converted value in the target unit, the measurement category (e.g. 'length', 'temperature', 'data size'), and the numeric conversion factor used to perform the conversion.
Example use cases
Recipe unit conversion for cooking
“I need to convert 3 cups of flour to milliliters for a metric recipe — what's the converted amount and conversion factor?”
Data storage size conversion for engineers
“How many GiB is 500 MB? Give me the exact value and tell me what the conversion factor is.”
International distance conversion for travel
“Convert 10 kilometers to miles so I can understand the distance on a US road sign.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/data/unitsWhen to prefer
Use this endpoint when an agent needs programmatic, reliable unit conversion across a broad set of physical and digital measurement categories including temperature, data sizes, and cooking volumes. It is especially useful when the conversion factor itself is needed (not just the result), or when handling user requests phrased as natural expressions like '10 km to miles'. Prefer this over hardcoded conversion logic when coverage across many categories is needed in a single consistent API.
Side effects
- Unrecognized unit name returns an error (e.g. misspelled or non-standard unit abbreviation)
- Incompatible unit categories (e.g. trying to convert km to kilograms) returns a category mismatch error
- Missing or malformed 'input' query parameter results in a 400 Bad Request
- Network or server unavailability returns 5xx error
